The specific hardware chip generation used in the phone.
In the old days—the DCT3 days—this would have been a hardware hack. He would have had to solder wires to the PCB, use an EEPROM programmer, pray he didn't fry the board. It was surgery.
Unlike DCT3, where codes were generated simply by IMEI, DCT4 requires two pieces of data:
Because DCT4 phones operate on obsolete or rapidly retiring 2G/3G networks, carriers no longer actively support or restrict these devices. Unlocking them is widely considered a safe, legal preservation effort. The Legacy of the DCT4 Calculator nokia dct4 calculator
